Moody's found Trump's plan would cost the economy 3.5 million jobs and increase the unemployment rate to 7 percent. Moody's says Trump's plan would add $1 trillion to the deficit in 2020, the last year of his term.

The deficit and the debt aren't the same thing. Deficit is the imbalance in the budget, but national debt is all the money the country owes.

Other estimates on how much Trump's plan would increase the deficit are in a similar range. The Tax Foundation says the federal deficit would increase by over $10 trillion over a decade, and the Tax Policy Center says Trump's plan would produce deficits of $11.2 trillion.

Clinton got that $5 trillion national debt increase from the Committee for a Responsible Federal Budget. It used the Tax Foundation's analysis to calculate how much Trump's plan would add to the national debt and found it would add $5.3 trillion over a decade. The committee says Clinton's plan would increase the debt by $200 billion.
